Smart Signal Processing #

What the package can do for you #

This package provides frequently used functions for signal processing:

• Computes mean values, variance, standard deviation.
• Applies windowing (apodization functions) with exponential or Gaussian shapes to an array
• Applies the Fast Fourier Transform, to an array.
• Calculates the power or magnitude of a complex-valued array
• Phase-shifts (rotates in the complex plane) the a complex-valued array

The major API functionalities #

• classes Sigma, BaseLine, WinFunc,FFT, Phase.

Examples:

• Multiplication with an exponential:

  WinFunc.expMult(array, decayFactor, false, "0");

• Compute Fourier Transform:

  FFT.transform(reals, imags);

• Compute magnitude:

  Phase.magnitude(reals, imags, true)

• Compute variance in a region:
  Sigma.variance(array, ixstart, ixend)
